"peditious and effective manner. The im designed for operation more ram.1'. mn'rz; or Tamra, Kansas To all whom it may concern:

Be it knownthat LPAUL P. LANfrz,1a citizen of the Republic ofswitzerlanmresiding at Tampafln the county of, Marion, State of Kansas,haveinvented certain new and use-V ful Improvements inStacking-Machines, of which the following is a full and exactspecification.

. The present invention relates to machines for stacking grain and thelike,

and' aims to provide-an'improved portable apparatus for stackingmaterial of this character in an exprovements are particularly in thestacking of headed grain,

fupon a wheel support comprisinga truck V 2 having the bed portion &adapted to support a turn-tahle (hbetween which and the though the useofthe same is not confined to such material alone. a

One of the Objects of theinvention is to devise a construction in. whichthe stacker frame is provided with means for readily adjusting the frameat desired properly positioning: the head or delivery end df the framewith reference to the stack being formed. For this purposeprovision 1smade for effecting movenwnt-ofthe stackmg frame and the conveyer -arr1edthereby about various verticaland horizontal axes for obtaimng the.required. adjustments in position of the head of theframe.

It.1s also an ()hjtCi to provide a convenient and readily operatedmechanism for effecting the required adjusting movements withoutinterrupting the movements of the conveyer.

h A further object is to-equip the apparatus for portable use byproviding! a suitable. wheelsupporting means adapteil to permit .all thenecessary adjustments of the stacking frame while reliably andeffectively supporti claims.

It is-a further object to devise a strong. durable and compactconstruction and arrangement for embodying the proposed improvements.Other minor objects incident. to the foregtnn; wll'l appear in thecourse intervals for v headed grain. so that "any loss of 'the gain" endof which is also liked ai'drive sprocket dr ve chain 34 01 "in Fig.

Ellnl'ower sprocket wheels 1'3 arefixed to a foot shaft- 30, toone driven by a belt 52 from a pulley 54 having suitable clutchconnection with the engine 56 also mounted on the table 6.

Means is provided for adjusting the angle and elevation of the stackerframe as fol-. lows. To the shaft 46 is fixed a worm gear 58 in meshwith a worm 60 mounted in the bracket 62 011 the table 6 and adapted tobe turned by the hand-wheel 64. To the shaft l6 is also secured a-leverarm 66, the oppo site end of which is pivotally connected to the shaft38. For cooperating with the arm- 66 in the support of the stackerframe, a supporting frame 68 is provided, this latter frame beingpivotally mounted in brackets L 70 at opposite sides of the centralvertical axis 10, and having the fork projections 72 carrying rollers 74for. engagement with the guide rails 76 secured at opposite sides of theframe 12.- The greater portion'of the weight of the stacker frame is atthe rear of the shaft 38, so that the frame 12 tends to throw thesupporting frame 68 to the rear, and for holding said frame 68 inposition for supporting the stacker frame at the proper angle to theaxis 38 rwindlass 78 is provided on the table 6, havi lg the cable 80extending around the guide .rolle'r s2 on said table and connected to abail 84 at-- tached to the opposite sides of 'said frame 68. A pawl 86and ratchet wheel SWo'n the Windlass serve to retain the partsin therequired position.

From the foregoing it will be apparent that a comparatively simple andefficient apparatus has been devised for carrying out the objects of theinvention. The grain or material to be stacked is fed to the receivingportion 12 of-the stacker, whence it is carried by the conveyer out overthe delivery end of the stacker on to the stack. By'the arrangement ofadjusting means provided, it is clear that theposition of the stackermay be readily altered in order to vary the location of its delivery endwith reference to thestackingpoint, as required. In accomplishing thisadjustment of the apparatus, it will be observed that the entireapparatus may be swung about the axis of the pin 10; or the stackerframe ma be moved about the axis of the shaft 38 iiy operation of theWindlass 78; the lower end of said frame may be raised or lowered b theopen ation of the wheel 68; and the rame ma be bodily swung about theaxis of the shaft 46 and also intermediate adjustments ob tained by thecombined manipulation of the wheel 68 and Windlass 78, as will bereadily understood. A clutch lever 90 of suitable length (see Fig. 1)may be provided for convenient control of the engine from the stack, ifdesired.

While the foregoing represents what is now deemed to constitute thepreferred form of embodiment of the lmPIOVGITIGIIl'S, the right 18'reserved to such formal changes and modifications as may fairly fallwithin the scope of the appended claims.
